| 摘要 |
The present invention relates to a pneumatic tire which includes a sealant layer formed on the inner surface thereof. The sealant layer includes 100 parts by weight of a butyl rubber, 200 to 400 parts by weight of polyisobutylene, 10 to 100 parts by weight of inorganic additives, 1 to 15 parts by weight of a vulcanizing agent, 0.01 to 10 parts by weight of foamed bead particles. The pneumatic tire can reduce noise in the tire by dispersing noise energy which causes resonance in the tire or changing generated frequencies. |
